While some of the other options on this list focus exclusively on technical, on-page or off-page ranking factors, SEMrush is one of the few solutions that provides robust tools for all three areas of SEO auditing. The technical site audit tool will analyze your website and detects more than 130 different errors. There’s also an on-page SEO checker that ensures that your pages are optimized to rank for chosen keywords and a backlink audit tool that can detect toxic or low-quality links.

As with other all-in-one solutions, Moz offers SEO analysis tools that help with technical, on-page and off-page SEO auditing.
When to Use It: As an SEO audit tool, Moz can be very effective for digital marketers that need to audit every aspect of their website performance. An all-in-one audit tool is a great starting point for identifying issues, even if you may end up needing more specialized software to drill down and correct the most persistent technical issues. Moz has one of the strongest on-page optimization tools on this list and we also like how you can schedule regular crawls, track changes in issues over time and even monitor the impact of your changes on desktop vs mobile devices.
Pricing & Access: Moz offers a 30-day trial so you can test out their SEO audit tool before subscribing. The basic subscription package starts at $99/month.
Overview: Screaming Frog builds a product called SEO spider, which users can deploy to crawl a website and identify technical and on-page SEO issues. While SEO Spider wouldn’t be described as an all-in-one platform, it does an exceptional job of detecting technical SEO issues on websites of all sizes.
When to Use It: Using the free version of SEO spider, digital marketers can find broken links, link errors, 301 redirects, poorly optimized HTML tags, duplicate pages and a range of other technical and on-page SEO issues across a maximum of 500 URLs. The paid version of the SEO Spider includes even more features, including new customization options and powerful integrations with Google Analytics and Google Search Console.
SEO Spider is primarily report-based, so you won’t see a lot of great visualizations and dashboarding here. Still, this is one of the best tools for crawling large websites and identifying technical SEO problems that need to be addressed.
Pricing & Access: There’s a free version available, but users are only able to crawl 500 URLs. For additional memory, storage and features, you’ll have to purchase a single-user license starting at ￡149/year.
Overview: If you’re auditing your SEO to improve your rankings with Google, why not collect at least some of your feedback using Google’s own webmaster tools? With Google Search Console (GSC) as your SEO audit tool, you can do exactly that.
When to Use It: If you don’t already have the Google Search Console installed on your website, you definitely should. This simple website plug-in offers, absolutely for free, many of the same diagnostic capabilities that are seen in paid SEO tools. You’ll be able to identify crawl errors and blocked URLs on your website while monitoring the index status of every single page you publish. Under the optimization tab, GSC helps you organize structured data and optimize HTML on your website, including meta descriptions, title tags and headers.
Pricing & Access: Google Search Console is a free SEO audit tool offered by Google to anyone with their own website.
Overview: In the past, Alexa maintained its own website ranking system called “Alexa Rank” that ranked all websites on the Internet by popularity. Now, having been acquired by Amazon, Alexa provides SEO analysis tools for marketers and digital marketing agencies.
When to Use It: Alexa’s site audit tool is a powerful, all-in-one platform that was purpose-built to compete with tools like Moz and SEMrush that also provide comprehensive SEO auditing.

If you’re having issues with high bounce rates or low click-through rates on your web pages caused by poor page speed and long loading times, you should analyze your website with Google PageSpeed Insights.
